audiopython 0.0.19

A package with functionality for offline audio processing

audiopython

Introduction

This is a Python library for working with audio. It comes in two flavors - a regular Python version called pyaudiopython, contained in the pyaudiopython directory, and a Cython version called caudiopython, contained in the caudiopython directory. There is a separate directory called audiopython that is set up for building a package - at the moment, this directory contains a copy of the Cython version.

You can install this library from PyPi by running the command pip install audiopython. This will install the Cython version, which is only compiled for Windows at the moment. You can also build the package yourself on your own computer if you wish. Or you can use individual modules in the pyaudiopython or caudiopython directories.

The package is divided into 8 modules:

audiopython.analysis

Tools for spectral analysis and analysis of audio waveforms. Many of these tools are based on formulas from Florian Eyben's "Real-Time Speech and Music Classification," published by Springer in 2016. Among other things, this module computes spectral centroid, entropy, slope, and flatness.

audiopython.audiofile

This module is for reading and writing audio files, using either the pedalboard library or using (slower) code provided here.

audiopython.granulator

Funtionality for grain extraction

audiopython.operations

This module has various operations that can be performed on audio, such as spectral frame swapping, equal energy forcing, dc bias removal, and beat envelope generation.

audiopython.plot

Plotting functionality for audio and spectrum

audiopython.sampler

Tools for extracting samples from audio

audiopython.spectrum

Tools for spectral analysis

audiopython.synthesis

Tools for generating simple waveforms

Dependencies

You will need the following Python libraries: matplotlib, numpy, pedalboard, regex, scipy. You will also need Cython if you want to build the Cython version.

Building

To build this package, run python -m build.
